The technical idea of the present invention relates to an electric sterilizer capable of drying and sterilizing an object.

In general, in order to sterilize objects such as baby bottles and toothbrushes, a hot water sterilization method in which an object is put in boiling water to sterilize, a steam sterilization method in which an object is sterilized using hot steam, etc. have been used. However, in the case of the hot water sterilization method, there may be a problem of generating environmental hormones from the plastic material object, and in the case of the steam sterilization method, there is a cumbersome and inconvenient problem of evaporating water to obtain steam.

Recently, in order to improve the problems of the hot water sterilization method and the steam sterilization method, an ultraviolet sterilization method in which an object is sterilized by irradiating ultraviolet rays is mainly used. At this time, the object that has been sterilized and dried can be stored and used in the electric sterilizer. When the door of the electric sterilizer is opened and closed, the humidity inside the main body of the electric sterilizer changes according to the external humidity. In particular, even if the inside of the body is exposed to the outside for a short time during a season or weather with high external humidity, the humidity inside the body is high, so that bacteria in the air may be introduced, and there is a problem that bacteria increase inside the body.

According to a preferred embodiment, the side ultraviolet irradiators 151 and 152 and the upper ultraviolet irradiators 161 and 162 may include an ultraviolet lamp, and the lower ultraviolet irradiator 170 is an ultraviolet light emitting device (UV LED). ) may be included. 1 shows an example in which two UV irradiators and one UV irradiator are positioned at the bottom of the electric sterilizer 100, respectively, on the inner side and upper side of the electric sterilizer 100, but various numbers on each of the side, upper and lower parts It would be okay if the UV irradiator of the

The door of the electric sterilizer 100 is disposed to open and close the inside of the main body, and the door may be configured to close the doorway while sterilizing and drying the object is in progress, and to bring in and take out the object. It may be configured to open a doorway. In addition, the object in the electric sterilizer 100 may be sterilized by ultraviolet rays irradiated by the plurality of ultraviolet irradiators described above. In exemplary embodiments, the above-described ultraviolet irradiators may be configured to emit ultraviolet rays in a wavelength band suitable for sterilization, for example, a UV wavelength band. Although not shown in FIG. 1, the electric sterilizer 100 may further include an electric heater such as a PTC (Positive Temperature Coefficient) heater as a drying module (not shown) to provide a function of drying an object, and A drying function for the object may be performed based on air heating by the air and air circulation operation through a suction fan (not shown).

Meanwhile, the electric sterilizer 100 may include a microcomputer 110 that performs an overall control operation, and a door detection sensor 120 that detects opening and closing of the door. The microcomputer 110 may perform electrical and/or mechanical control operations for various components provided in the electric sterilizer 100, and as an example, a safe storage function (or , automatic drying function) can be performed a series of operations. In addition, the door detection sensor 120 may detect whether the door of the electric sterilizer 100 is opened or closed, and may provide the detection result to the microcomputer 110 . The safe storage function described above may be controlled by the microcomputer 110 using the detection result from the door detection sensor 120 .

On the other hand, according to an embodiment, a rotary table 130 whose rotation is controlled by a predetermined motor (not shown) is disposed inside the main body of the electric sterilizer 100 , and the cradle post 140 is disposed on the rotary table 130 . As it is placed on the pedestal, when the rotary table 130 is rotated, the holder column 140 may also be rotated. Accordingly, the objects mounted on the cradle post 140 may be rotated inside the main body while the sterilization and drying operations are performed. In addition, the electric sterilizer 100 may further include a humidity sensor 180 , and the humidity sensor 180 may be disposed at any position inside the electric sterilizer 100 , and the humidity sensor 180 detects the humidity. The result is provided to the microcomputer 110, and the microcomputer 110 may further use the humidity detection result to control the operation according to the safe storage function.

The electric sterilizer 100 can perform normal sterilization and drying functions according to the user's selection, and after the normal sterilization and drying functions are completed, the user can use the object by storing it inside the main body of the electric sterilizer 100 . there is. At this time, the door of the electric sterilizer 100 may be frequently opened and closed in order to take out or put an object, and the humidity of the inside of the main body increases according to the external environment. In particular, when the external environment corresponds to a season or weather with high humidity, external moisture quickly flows into the body, which increases the humidity inside the body and causes bacteria in the air to enter the body. can be easily propagated.

According to an exemplary embodiment of the present invention, the electric sterilizer 100 may operate in a safe storage mode, and when an object is stored in the electric sterilizer 100 after performing normal sterilization and drying functions, the electric sterilizer 100 It can be determined whether the door of can be restrained As an example of operation, the electric sterilizer 100 may determine whether the humidity inside the main body is increased by continuously or periodically determining the humidity inside the main body, or performing a humidity sensing operation after determining that the door is opened, When the sensed humidity exceeds a predetermined reference value, the automatic drying function described above may be performed.

On the other hand, in the embodiments to be described later, examples in which various operations according to the safe storage function and operations according to the normal sterilization and drying functions are performed according to different methods through different various judgment criteria will be described. The sterilization and drying operation may be performed substantially the same as the normal sterilization and drying operation. In addition, in some embodiments, only the drying operation may be described in relation to the safe storage function for convenience of description, but as described above, the sterilization operation may be further performed together with the drying operation in the safe storage function as described above.

2 is a flowchart illustrating a method of operating an electric sterilizer according to an exemplary embodiment of the present invention.

Referring to FIG. 2 , the power of the electric sterilizer is turned on (S11), and a normal sterilization and drying function of an object may be performed according to a user's selection (S12). In addition, even after the normal sterilization and drying functions are completed, the object may be stored inside the body.

The humidity inside the main body of the electric sterilizer may increase due to reasons such as the user does not close the door of the electric sterilizer after opening it, and the electric sterilizer may generate a result of detecting the door opening through a door detection operation (S13). In addition, as the door open is detected, it may be determined whether the safe storage function of the electric sterilizer is currently selected (S14). A sensing operation may be performed (S15).

For safe storage of the object, a reference value of the humidity inside the body is set, and it may be determined whether the detected humidity exceeds the reference value (S16). If the detected humidity does not exceed the reference value, the automatic drying operation is not performed, but when the detected humidity exceeds the reference value, the automatic drying operation may be performed (S17). In addition, even if the detected humidity does not exceed the reference value, the door of the electric sterilizer is opened again afterward, and the humidity inside the main body may be further increased. When the internal humidity exceeds the reference value, the automatic drying function according to the embodiment of the present invention may be performed. As an example of an operation, when an opening of the door of the electric sterilizer is sensed, the humidity sensing and comparison operation may be periodically performed even if the humidity inside the main body does not exceed the reference value. Alternatively, when the door opening of the electric sterilizer is detected and the humidity inside the body does not exceed the reference value, the determination operation for automatic drying is terminated, and when the door is detected again after that, the automatic drying is performed. A determination operation may be performed for this purpose.

Meanwhile, although it has been described in the above-described embodiment that the humidity sensing operation for the automatic drying function is selectively performed based on the result of detecting the opening of the door, the embodiment of the present invention is not limited thereto. As an example, the humidity sensing inside the body may be continuously or periodically performed regardless of the opening and closing of the door, and when the humidity inside the body exceeds a reference value, the automatic drying function described above regardless of whether the door is opened This may be done.

3 is a graph showing an example of a change in humidity inside the main body of the electric sterilizer of the present invention.

Referring to FIG. 3 , as the normal sterilization and drying functions are performed, the humidity inside the body may be lowered, and as an example, the humidity inside the body may be lowered to a very small value according to a user's selection and a predetermined setting method. Thereafter, as the door of the electric sterilizer is opened, the inside of the main body is exposed to external air, and thus, the humidity inside the main body may gradually increase. If the safe storage function according to the embodiment of the present invention is not applied, the humidity inside the body is maintained at a high value.

On the other hand, as the safe storage function according to the embodiment of the present invention is applied, the automatic drying function is performed at a specific point in time regardless of the user's selection, and accordingly, the humidity inside the body may be lowered to a predetermined set humidity. As an example, a humidity sensing operation inside the main body may be performed in response to detecting the opening of the door of the electric sterilizer. An action may be performed. In addition, the humidity detection result is compared with a predetermined reference value, and when the humidity inside the body exceeds the reference value, an automatic drying function may be performed. In FIG. 3, the set humidity according to the automatic drying function is normal sterilization and drying Although the same example as the humidity after performing the function is illustrated, the set humidity according to the automatic drying function may be set to various values.

In addition, the electric sterilizer 200 may further include an object detection sensor 230 for detecting objects mounted inside the electric sterilizer 200 and the aforementioned humidity sensor 240 to perform disinfection, and also a microcomputer ( 210) and a door detection sensor 220 may be further included. Also, the electric sterilizer 200 may further include a drying module 270 for lowering the humidity inside the main body by performing a drying operation.

The object detection sensor 230 may detect whether one or more objects are present in the electric sterilizer 200 , and may provide a result of detecting the object to the microcomputer 210 . As an example, the object detection sensor 230 may detect objects through various methods, and according to an embodiment, the object detection sensor 230 is positioned on each of the plurality of cradles so that the object is mounted on the corresponding cradle. It is possible to detect whether or not it has occurred and generate the detection result. In addition, the humidity sensor 240 may output a result of detecting the humidity in the electric sterilizer 200 , and the humidity sensor 240 may operate according to various driving conditions. As an example, the humidity sensor 240 may periodically or continuously perform a humidity sensing operation even after the normal sterilization and drying functions are completed, or detect the humidity based on the result of detecting the opening of the door of the electric sterilizer 200 . action can be performed. Alternatively, the humidity sensor 240 may perform a humidity sensing operation based on a combination of a result of detecting the door being opened and a result of detecting that an object is present inside the body.

The microcomputer 210 may include an automatic drying determination module 211, and the automatic drying determination module 211 performs various determination operations for performing the automatic drying operation according to the above-described embodiment as the safe storage function is applied. can be done As an example, the automatic drying determination module 211 may include reference information including various reference values and set values, and automatic drying operation is performed through detection results from various sensors and a processing operation using the reference information. You can decide whether to do it or not.

As an example of operation, the automatic drying determination module 211 may compare the humidity detection result provided from the humidity sensor 240 with one or more reference values according to the result of detecting the door open from the door detection sensor 220 . As an example, as the door of the electric sterilizer 200 is opened, the humidity inside the body gradually rises, and as the humidity detection result exceeds the reference value, the automatic drying determination module 211 determines the timing to perform the automatic drying operation. can judge

In addition, the automatic drying determination module 211 may determine whether an object exists in the main body according to the detection result from the object detection sensor 230, and performs an automatic drying operation when the object is present in the main body. can be judged as The microcomputer 210 may control the automatic drying operation by outputting various control signals (Ctrl) based on the determination result from the automatic drying determination module 211. As an example, the microcomputer 210 may include the drying module 270. By driving the above-described automatic drying function can be performed. In addition, in the safe storage function, a sterilization operation may be further performed along with an automatic drying operation, and the microcomputer 210 uses the UV lamp 261 and the UV LED 262 through the lamp driver 251 and the LED driver 252. drive can be controlled. In addition, although not shown in FIG. 4, a rotary table (not shown) whose rotation is controlled by a motor is further provided inside the main body of the electric sterilizer 200, and as the rotary table rotates, sterilization and drying operations in the safe storage function Objects can be rotated inside the body while this is being performed.

According to the embodiment shown in FIG. 4 , the automatic drying determination module 211 determines whether or not the safe storage function is applied, and the automatic drying operation through the processing operation using the detection results and reference information from various sensors A final decision can be made as to whether or not to carry out For example, in the case of an object that has been subjected to normal sterilization and drying operation, since the sterilization process has already been performed, the automatic drying operation for the object does not need to be performed unnecessarily frequently, and accordingly, whether to perform the automatic drying operation The operation of determining , may be optimized using the above-described various detection results and reference information. In addition, in the case of the normal sterilization and drying function, compared to the case where it is performed for a preset time according to the user's selection, in the case of the automatic drying operation, only the amount of time required to lower the humidity inside the body to the set humidity or less based on the detected humidity It may take time, and the object can be safely stored through a relatively short internal processing.

5 is a graph showing various examples of setting the humidity inside the main body of the electric sterilizer.

Referring to FIG. 5 , as the normal sterilization and drying functions are performed, the humidity inside the body may be lowered to a very small value. Thereafter, the door of the electric sterilizer is sensed to be opened, and it may be determined whether to perform the automatic drying function according to the humidity detected inside the main body immediately after the door is opened or after a predetermined time. As an example of an operation, a comparison operation using the humidity detection result may be performed after a predetermined time after the door is opened, or a comparison operation using the humidity detection result may be performed after the door is closed. Alternatively, as an embodiment that can be implemented, the humidity inside the body is continuously or periodically detected, and the operation of determining whether to perform an automatic drying function using the detected humidity is based on the result of detecting the opening of the door. It may be selectively performed according to the

The sensed humidity is compared with a reference humidity (α) corresponding to a predetermined reference value, and when the sensed humidity exceeds the reference humidity (α), the automatic drying function in the above-described embodiments may be performed. Accordingly, the humidity inside the main body of the electric sterilizer gradually increases and then decreases again as the automatic drying function is performed, and the humidity inside the main body is lowered to a level corresponding to a predetermined set humidity β. At this time, in the normal sterilization and drying operation, it is performed for a predetermined time according to the user's selection, whereas in the automatic drying operation according to the safe storage function, the humidity inside the body is continuously compared with the predetermined setting humidity (β) , when the humidity detection result is lower than the set humidity (β), the automatic drying operation may be terminated.

6 is a flowchart illustrating a method of operating an electric sterilizer according to exemplary embodiments that can be modified.

Referring to FIG. 6 , according to a user's selection, the electric sterilizer may perform normal sterilization and drying functions for objects (S21), and whether the door of the electric sterilizer is opened may be continuously detected (S22). As it is determined that the door is open, the humidity inside the body may be detected (S23), and when the door is in an open state, the humidity inside the body may continue to increase. In the closed state of the door, constant humidity inside the body may be detected.

According to the above-described embodiments, the sensed humidity is compared with a reference value (S24), and when the sensed humidity exceeds the reference value, an automatic drying function may be performed (S25). In addition, the humidity may be periodically or continuously detected while the automatic drying function is being performed, and it may be determined whether the detected humidity falls below a set humidity (S26). In addition, when the humidity falls below the set humidity, the automatic drying function may be terminated (S27).

According to the above embodiment, the operation of sensing humidity and determining the humidity in response to whether the door of the electric sterilizer is opened may be selectively performed, and the detection and determination operation may be performed after detecting that the door is closed. there is. Accordingly, after moisture from outside flows into the body while the door is opened, the humidity inside the body may be appropriately determined in a state in which the door is closed, and an automatic drying function may be selectively performed based on this.

On the other hand, a control operation for performing the automatic drying function may be performed as the door is opened, and when the humidity detected in the closed state of the door is less than or equal to the reference value, the control operation related to the automatic drying function may be terminated. can That is, in response to determining that the sensed humidity is equal to or less than the reference value, the operation of detecting the humidity inside the body and comparing it with the reference value may be terminated. After that, when it is detected that the door of the electric sterilizer is opened again, the control operation for performing the automatic drying function is performed again, and accordingly, the automatic drying function is based on the result of detecting the humidity inside the body and comparing it with the reference value Whether to perform may be judged again.

Meanwhile, although not described in the above embodiments, when the automatic drying operation is performed, a notification operation indicating this may be performed in various ways. That is, since the automatic drying operation according to the safe storage function according to the embodiments of the present invention can be performed regardless of a user's selection, a display provided in the electric sterilizer notifies that the automatic drying operation is being performed, or a voice It may be notified that an automatic drying operation is being performed through a means for generating and outputting .

7 is a flowchart illustrating a method of operating an electric sterilizer according to another deformable exemplary embodiment of the present invention.

Referring to FIG. 7 , it may be determined whether a sterilization and drying function will be performed (S31), and whether the sterilization and drying function will be performed by various methods such as a user's selection and a self-determination of the electric sterilizer. can When the sterilization and drying function is performed, it is determined whether the function is performed in the safe storage function mode (S32), and when it is determined that the function is performed in the safe storage function mode, when the drying function is performed, Whether the humidity falls below a predetermined set humidity may be continuously or periodically detected (S33). Also, when the sensed humidity falls below the set humidity, the sterilization and drying functions may be terminated.

On the other hand, if it is determined that the sterilization and drying function is not performed in the safe storage function mode (or if it is determined that it is a normal sterilization and drying function), the sterilization and drying function is performed according to a preset method in the electric sterilizer, For example, the drying function may be performed for a predetermined set time (S34). As an example, the humidity inside the main body according to the normal sterilization and drying function and the set humidity in the safe storage function mode may be set differently.

On the other hand, in this embodiment, it has been described that the sterilization operation is further performed in the safe storage function, and as an example, the above-described sterilization operation is more effective because external moisture is introduced into the body to have a state in which bacteria in the air have already been propagated. It may be appropriate to do so. As an example, it may be determined whether the sterilization operation is performed based on information such as a duration for which the door is opened, a degree of humidity inside the body, and an elapsed time since the door is opened. If the open state of the door lasts a long time and the internal humidity is relatively high, it is highly likely to correspond to a state of bacterial propagation. will be able

In addition, when the power of the electric sterilizer is turned off, whether the door is opened may not be detected. In addition, in this case, even when the humidity inside the body is not high because moisture is not high on the outside, the object may correspond to a state in which the object is exposed to bacteria. According to an embodiment, the electric sterilizer may detect when the power is turned off, and when it is determined that the power is off, the electric sterilizer may perform the automatic drying function described above regardless of whether the door is opened or whether the humidity inside the body is detected. Alternatively, if it is determined that the power is off, the automatic drying function described above may be performed based on the humidity detection result regardless of whether the door is opened. Alternatively, when it is determined that the power has been turned off, the sterilization operation may be further performed together with the automatic drying function.
